Abstract: A tool and an associated method for removing a prosthetic implant includes a lateral tool, a first impact tool secured to the lateral tool, a medial tool, and a second impact tool. Although the tool can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. Both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface.

Abstract: A guide operates in the creation of a bone spur to facilitate harvesting a quadriceps tendon and includes an end having a width equal to a desired graft width with a terminal slope equal to a cutting angle desired. In use, the guide may be initially positioned parallel to the femur to form guide cuts in the patella. The guide is then rotated ninety degrees to allow an angled cut at the guide cut. The guide is again rotated, this time one hundred eighty degrees and a second angled cut made on the other guide cut. A final lateral cut is made and the bone spur may be lifted from the patella.
